FORGE.

Specification of Letters Patent.

Application filed October 9, 1906. Serial No. 338,161.

Patented Jan. 15, 1907.

To all whom it may concern:

Be it known that I, RODERICK KRAATZ, a citizen of the United States, residing at Carbondale, in the county of Jackson and State of Illinois, have invented certain new and useful Improvements in Forges; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a forge, and particularly to a structure adapted to be adjusted relative to the work to be heated.

The invention has for an object to provide a novel and improved construction by which the forge may be vertically adjusted upon its supporting-standards and retained at such adjustment, together with means at the front of the forge by which structures adjacent to the part to be heated may be protected from the blasts.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a side elevation of the invention applied to a truck or car. Fig. 2 is a plan view thereof. Fig. 3 is a vertical sectional view on line 3 3 of Fig. 2, and Fig. 4 is a detail sectional view showing a latch.

Like numerals of reference parts in the several figures of the drawings.

The invention is adapted for any application of a forge, but particularly for adjustment relative to a car or trucksuch, for instance, as shown in Fig. 1. The frame 1 of the truck is provided with a bearing-box 2 and a wheel 3 to travel on the rail 4, mounted upon a tie 5 or other suitable support. The upper portion of this car is provided with an arm 6, having an extended end 7, which in the practical use of cars of this structure frequently becomes bent or distorted, and in the instance where such cars or trucks are used in connection with kilns or chambers for treating the material carried thereby this end portion must be bent back to its original condesignate like formation in order to permit the continued use of the car or truck.

The forge when used in connection with work of the character just described is mounted upon a fixed support adjacent thereto by means of standards 8, which support a cross-bar 9, having vertically-extend ing posts 10 thereon. These posts are adapted to travel in sleeves 11, formed at the corners of the forge-box 12, as shown in Fig. 2, so as to guide the sliding movement of said box. The raising of the box is accomplished by means of the rock-shaft 13, mounted in bearings 14, depending from the frame, such rock-shaft being connected by the crank-arm 15 and the link 16 with the end wall 17 of the forge-box. This link is protected against injury by a keeper 18, mounted on the standards 8. The extended end 19 of this keeper is provided with ratchet-teeth 20, which oooperate with a pawl 21, pivotally mounted on the operating-handle 22, carried by the end of the rock-shaft 13. The connecting link 16 is duplicated at the opposite end of the box,'so that an even raising movement is secured.

As shown in Fig. 2, the forge-box is divided into several compartmentsthat is, a central compartment 23, having a blast-box 24 therein, and the connecting air-pipe. 25, extending thereto. This blast-box is provided with the usual shaker, having the rod 26 extended therefrom to the rear of the forge. At the opposite end of the box fuelcompartments 27 are formed, the partition thereof comprising parallel walls 28, between which a sliding gate 29 is mounted, this gate being connected by a link 30 with a shifting lever 31 thereof, which is pivotally mounted at its lower end upon the lug 32 and provided with a handle 33 at its upper portion. By this construction the coal may be readily fed to the forge-chamber or the fuel-comartment cut ofi therefrom, as found desirable. The front of the forge-box is provided with pivoted doors 34, each of which is of angular construction and mounted on the end wall 17 of the forge-box by means of the pivot 35, while the free edge of these doors is provided with a pivoted latch 36 (shown clearly in Fig. 4 of the drawings) and adapted to embrace or engage the work and hold the doors inposition relative thereto, so as to prevent injury to any adjacent portion of the structure being heated. The forge blast may be driven in any desired manner. For instance, the pipe 25 is extended to the fanbox 37, as shown in Fig. 2, and the blast-fan therein is provided with a pulley 38 upon its shaft, over which the belt 39 extends from a driving-pulley 40. This driving-pulley carries upon its shaft a pinion 41, which meshes with a gear 42 on the shaft 43, the extended end of which is formed with a hand-crank 44 of the usual character, all of these parts being supported in an extended frame 45 at the reargof the forge-box, while the parts of the driving mechanism are protected from the heat by means of a shield 46, extending upward at the rear of the forge.

In thezoperation of the invention the forge is adapted to be adjusted to the side of the car or other object to be heated, and the portion to be forgedfor instance, the extended arm-is adjusted so as to be in contact with the fire and thoroughly heated thereby, so 1 that it may be bent to its proper position without the necessity of disassembling the parts of the car. This is particularly useful in cars or trucks used in the treatment of railway-ties, where the supporting-arm thereon being effected by the acid used in such treatment becomes badly bent or distorted,

so that it will not enter the compartment.

used in treating the material, and the present invention is adapted to adjust the forge to such a part for heating the samepreparatory to restoring it to the original position. The angled doors inclosing the front of the forge prevent the loss of fuel therefrom and also protect the portion of the car or truck from heat which is adjacent to the arm, and

- the hook upon these doors is adapted to engage the arms and retain them in proper position. The vertical adjustment of the forge-box which is to be raised to the desired elevation brings the fire in proper relation to the work to be heated. In case it be desired to mount the forge in a fixed position andto bring the cars over the same the gates at the opposite fuel-boxes may be drawn backand the angled doors swung open, so as to allow a free passage for the structure to be heated directly above the fire-box.
